Description

本発明は、鉄筋コンクリート建物の柱型枠を形成する型枠構造において、室内側の柱型枠せき板を透明樹脂板で成形し、室外側の柱型枠せき板を断熱パネルで形成し、柱型枠の４面を支える型枠側面補強材を鉢巻き形の締付金物で固定した柱型枠に関するものである。 INDUSTRIAL APPLICABILITY In the formwork structure for forming a pillar formwork of a reinforced concrete building, the present invention forms a pillar formwork weir on the indoor side with a transparent resin plate, and forms a pillar formwork weir on the outdoor side with a heat insulating panel to form a pillar. It relates to a pillar formwork in which a formwork side reinforcing material that supports the four sides of the formwork is fixed with a head-wound type fastener.

鉄筋コンクリート建物の柱を形成する型枠にコンクリートを打設する際、コンクリートは、材料を適切に選定し、施工性能に優れて硬化後の品質が確保されるように配合が行われると、通常は型枠の中にスムーズに打ち込まれ、しっかりと締め固めをしておけば耐久性のある柱を造ることができる。
しかし、コンクリートを打ち込みやすくすることは、流動性を高めることになり、その流動性に応じて材料分離抵抗性（コンクリートの粘性）を高めなければ、材料分離（粗骨材がモルタル部分から離れる現象）が発生する。
また、材料分離抵抗性を高めても、流動させれば骨材は沈み、流動しやすいモルタルは流れて分離する。
また、一般的にコンクリートの打設時には高周波バイブレーターを使用するが、高周波バイブレーターでコンクリートに振動を長く与えると骨材が沈み、材料分離が生じる。
材料分離をすると、モルタルの多い箇所ではひび割れが生じやすくなるものの、ジャンカ（コンクリートの表面に骨材が集まった「豆板」、コンクリートの内部が詰まっていない「空洞」、コンクリートの表面に空洞が見られる「巣」等を総称してジャンカと呼ぶ）はできない。
ジャンカができるのは、骨材が集まるような打ち込みが主原因である。
たとえば、長い斜めシュートでコンクリートを打ち込むと、粗骨材は転がって遠い方に骨材が集まり、モルタルは粘性が高いためシュート面に沿ってゆっくり流れ、シュートの下で分離する。
配筋された型枠内に斜めシュートを用いて打ち込む場合に、この分離を見逃すと、部分的に粗骨材が集まってジャンカができることがある。
また、ポンプ圧送による打ち込みは、材料分離を少なくさせる打ち込み方法の一つと考えられているが、打ち始めの時点や段取り替えの際に、配管内のコンクリートが落下することになり、骨材が先に走ってジャンカを造ることがある。
ジャンカができる要因にはいくつかのパターンがある。
（１）流動性が不足して未充てんになる場合。
（２）打込み速度が速く締固めが不十分になる場合。
（３）粗骨材が一部に集まる場合（この場合は、高周波バイブレーターで振動を与えてもモルタルは粗骨材の隙間を充てん出来ない）。
（４）モルタルが仮枠の隙間から抜け出して骨材だけが残される場合。
いずれも材料分離による影響が原因で発生する。
配筋状態や型枠の形状に応じた施工性能をもつコンクリートであれば、（１）や（２）の原因のジャンカはできないし、型枠を精度よく組み立てていれば（４）はあり得ない。
しかし、（３）の原因は案外と見逃されやすく、ポンプ圧送を用いた施工であるにもかかわらず、ジャンカが生じてしまうことがある。
順調に圧送されている段階では筒先のフレキシブルホースを水平にして打ち込むため、筒先からの落下高さは自ずと小さく、問題になるほどの材料分離は生じないが、ところが、型枠内のコンクリートをバランスよく打ち上げていくためには、筒先を移動する必要が生ずる。
その際には、フレキシブルホース内のコンクリートを一旦吐き出し、ブームを他の場所に移動して打込みを再開するが、ブームの中では斜めシュートの材料分離と同様の現象が起き、コンクリートの中で粗骨材が先行して吐き出されてしまう。
このように、型枠にコンクリートを打ち込む際は、常にジャンカの発生を予測し、事前に対策を講ずることが必要である。When placing concrete in the formwork that forms the columns of a reinforced concrete building, the concrete is usually mixed when the material is properly selected and the concrete is mixed so that the construction performance is excellent and the quality after hardening is ensured. A durable pillar can be made if it is smoothly driven into the formwork and firmly compacted.
However, making it easier to drive concrete will increase the fluidity, and unless the material separation resistance (viscosity of the concrete) is increased according to the fluidity, the material separation (the phenomenon that the coarse aggregate separates from the mortar part) ) Occurs.
Even if the material separation resistance is increased, the aggregate will sink if it is made to flow, and the mortar that is easy to flow will flow and separate.
In addition, a high-frequency vibrator is generally used when placing concrete, but if the concrete is vibrated for a long time by the high-frequency vibrator, the aggregate sinks and material separation occurs.
When the materials are separated, cracks are likely to occur in places with a lot of mortar, but junkers (“mameita” where aggregates are gathered on the surface of concrete, “cavities” where the inside of concrete is not clogged, and cavities can be seen on the surface of concrete. The "nest" etc. that are used are collectively called "junka").
The main cause of junkers is the driving of aggregates.
For example, when concrete is driven with a long diagonal chute, the coarse aggregate rolls and gathers in the distance, and the mortar is so viscous that it slowly flows along the chute surface and separates under the chute.
If this separation is overlooked when driving into the arranged formwork using an oblique chute, coarse aggregate may partially gather to form a junker.
In addition, driving by pumping is considered to be one of the driving methods to reduce material separation, but the concrete in the pipe will fall at the beginning of driving or at the time of setup change, and the aggregate will come first. I sometimes run to build a junker.
There are several patterns of factors that can cause junkers.
(1) When the liquidity is insufficient and it becomes unfilled.
(2) When the driving speed is high and the compaction is insufficient.
(3) When the coarse aggregate gathers in a part (in this case, the mortar cannot fill the gap of the coarse aggregate even if vibration is applied by the high frequency vibrator).
(4) When the mortar escapes from the gap of the temporary frame and only the aggregate is left.
Both occur due to the effects of material separation.
If the concrete has construction performance according to the reinforcement arrangement and the shape of the formwork, the junker that causes (1) and (2) cannot be used, and if the formwork is assembled accurately, (4) is possible. No.
However, the cause of (3) is unexpectedly easily overlooked, and even though the construction uses pump pumping, junkers may occur.
At the stage of smooth pumping, the flexible hose at the tip of the cylinder is driven horizontally, so the drop height from the tip of the cylinder is naturally small, and there is no problematic material separation, but the concrete inside the formwork is well-balanced. In order to launch, it will be necessary to move the tip of the cylinder.
In that case, the concrete in the flexible hose is once discharged, the boom is moved to another place and the driving is restarted, but the same phenomenon as the material separation of the diagonal chute occurs in the boom, and it is rough in the concrete. The aggregate is spit out first.
In this way, when concrete is poured into the formwork, it is necessary to always predict the occurrence of junkers and take measures in advance.

しかしながら、工事現場で一般的に用いられている木製型枠のほとんどは、厚手のベニヤ板（コンパネ）の片側表面にコンクリートの付着を防ぐよう、平滑にするための塗料が塗布された合板型枠のため、型枠内部の打ち込まれたコンクリートの状態を見ることができないためジャンカの生じた場所を特定することができず、従来は、職人の経験と感覚だけで高周波バイブレーター等を使用して対応してきたため、ジャンカの発生を未然に防ぐことは困難であった。 However, most of the wooden formwork commonly used at construction sites are plywood formwork coated with a smoothing paint to prevent concrete from adhering to one side of a thick veneer board (control panel). Therefore, since it is not possible to see the state of the concrete that has been driven into the formwork, it is not possible to identify the location where the junker has occurred. Therefore, it was difficult to prevent the occurrence of junkers.

発生したジャンカを補修する一般的な方法としては、ジャンカの程度によりＡ〜Ｅの補修方法がある。
Ａ．砂利が表面に露出していない場合。
補修は不要。
Ｂ．砂利が露出しているが、表面の砂利を叩いても剥落することがなく、はつり取る必要がない程度。
補修方法は、ポリマーセメントモルタル等を塗布。
Ｃ．砂利が露出し、表層の砂利を叩くと剥落する場合。
補修方法は、不用部分をはつり取り正常な部分を露出させ、ポリマーセメントペースト等を塗布後、ポリマーセメントモルタル等を充填。
Ｄ．鋼材のかぶりから、やや奥まで砂利が露出し、空洞も観られる場合。
補修方法は、不用部分をはつり取り正常な部分を露出させ、無収縮モルタルを充填する。
Ｅ．コンクリートの内部に空洞が多数見られる。
補修方法は、不用部分をはつり取り正常な部分を露出させ、コンクリートで打ち換える。このように、ジャンカを補修する作業には、多くの労力とお金が必要であった。As a general method for repairing the generated junker, there is a method for repairing A to E depending on the degree of the junker.
A. If the gravel is not exposed on the surface.
No repair required.
B. The gravel is exposed, but it does not come off even if the gravel on the surface is hit, and there is no need to scrape it off.
The repair method is to apply polymer cement mortar, etc.
C. When the gravel is exposed and it comes off when the gravel on the surface is hit.
The repair method is to scrape off unnecessary parts to expose normal parts, apply polymer cement paste, etc., and then fill with polymer cement mortar, etc.
D. When the gravel is exposed to the back from the cover of the steel material and the cavity can be seen.
The repair method is to scrape off unnecessary parts to expose normal parts and fill them with non-shrink mortar.
E. Many cavities can be seen inside the concrete.
The repair method is to scrape off the unnecessary parts to expose the normal parts and replace them with concrete. In this way, the work of repairing the junker required a lot of labor and money.

上記のような問題が発生しているため、半透明の樹脂を用いたパネル型枠が数社から販売されている。
その中でも日本プラスチック型枠工業会に所属する「天馬株式会社」が製造販売しているリサイクル可能な複合強化プラスチック製型枠、商品名「カタパネル」、さらに、「大和技研工業株式会社」が製造販売しているコンクリート打設用樹脂製型枠、商品名「セフコン」が一般に知られている。Due to the above-mentioned problems, panel formwork using translucent resin is sold by several companies.
Among them, recyclable composite reinforced plastic formwork manufactured and sold by "Tenma Co., Ltd." belonging to the Japan Plastic Formwork Industry Association, product name "Kata Panel", and manufactured and sold by "Daiwa Giken Kogyo Co., Ltd." The resin formwork for concrete casting, the trade name "Sefcon", is generally known.

このように、コンクリートを打ち込む際に型枠内部を観察することができる半透明製のプラスチック製型枠も市販されているが、プラスチック製型枠は金型を用いてプレス機により製作するため縦横のサイズが限定され、木製型枠のように縦横サイズを自由に製作することが困難であった。 In this way, translucent plastic formwork that allows you to observe the inside of the formwork when driving concrete is also commercially available, but the plastic formwork is manufactured by a press machine using a mold, so it is vertical and horizontal. The size was limited, and it was difficult to freely manufacture vertical and horizontal sizes like wooden formwork.

さらに、壁面のように平面状の型枠に用いるプラスチック製型枠は、前記の会社（天馬株式会社、大和技研工業株式会社）から販売されているが、柱の大きさに応じて使用することが可能な柱用のプラスチック製型枠は無かった。
特に、鉄筋コンクリート建物の場合は、柱は建物を支えるための最も重要な構造物であり、コンクリートを柱の型枠に打ち込む際、柱の内部のコンクリートの状態を把握して高周波バイブレーター等を的確な位置に挿入してジャンカの発生を抑えることが重要である。Furthermore, plastic formwork used for flat formwork such as wall surfaces is sold by the above companies (Tenma Corporation, Daiwa Giken Kogyo Co., Ltd.), but it should be used according to the size of the pillar. There was no plastic formwork for pillars that could be used.
In particular, in the case of a reinforced concrete building, the columns are the most important structure to support the building, and when concrete is driven into the formwork of the columns, the state of the concrete inside the columns is grasped and a high-frequency vibrator etc. is accurately used. It is important to insert it in the position to suppress the occurrence of junkers.

さらに、市販されているプラスチック製型枠は、いずれの製品も半透明のため、コンクリート打ち込んでいる最中の型枠内部のコンクリートの状態を正確に把握することが難しく、そのため、高周波バイブレーター等を的確な位置に挿入し振動時間を調整してジャンカを防ぐことが困難であった。 Furthermore, since all of the commercially available plastic formwork is translucent, it is difficult to accurately grasp the state of the concrete inside the formwork while concrete is being poured. Therefore, high-frequency vibrators, etc. are used. It was difficult to prevent junker by inserting it in the correct position and adjusting the vibration time.

ところが、柱型枠の内部には太い鉄筋が数多く設置され、生コンクリートを柱型枠に流し込む際、柱型枠が膨張、破壊するのを防ぐため数多くのセパレーターとプラスチックコーンが取り付けられていた。セパレーターとプラスチックコーンは、柱鉄筋を構築したあと柱鉄筋の建物外側に型枠を設置し、次に柱鉄筋の室内側に型枠を設置し、このように柱鉄筋の室外側と室内側に型枠を設置したのち、室外側の型枠と室内側の型枠をセパレーターとプラスチックコーンで固定していた。 However, many thick reinforcing bars were installed inside the column formwork, and many separators and plastic cones were attached to prevent the column formwork from expanding and breaking when pouring ready-mixed concrete into the column formwork. For the separator and plastic cone, after constructing the column rebar, the formwork is installed on the outside of the building of the column rebar, then the formwork is installed on the indoor side of the column rebar, and thus on the outdoor and indoor sides of the column rebar. After installing the formwork, the formwork on the outdoor side and the formwork on the indoor side were fixed with a separator and a plastic cone.

しかしながら柱型枠の内部に構築した太く数多い鉄筋の間の隙間にセパレーターを通して定位置にセパレーターを設置する作業は、太く数多い鉄筋の間の隙間にセパレーターを通す作業のため、鉄筋が邪魔をして所定位置にセパレーターを通すことが難しいという問題があった。 However, the work of passing the separator through the gap between the many thick and numerous reinforcing bars built inside the column formwork and installing the separator in place is the work of passing the separator through the gap between the many thick and numerous reinforcing bars, so the reinforcing bars interfere with it. There was a problem that it was difficult to pass the separator through the predetermined position.

本発明は、コンクリート建物の柱型枠にコンクリートを打ち込む際、柱型枠内部のコンクリートの状態を観察することができると共に、柱型枠を固定する際、セパレーターとプラスチックコーンを使わない柱型枠を提供することを目的とする。 According to the present invention, when concrete is poured into a pillar formwork of a concrete building, the state of the concrete inside the pillar formwork can be observed, and when fixing the pillar formwork, a pillar formwork that does not use a separator and a plastic cone is used. The purpose is to provide.
